I* Specication'forming part of Letters Patent No. 222,365, datedDecember 9, 1879; applicaizionfiled` p y April 16, 1879.

To all whom t may concern: v. j y Be it known that I, WILLIAM PHIP-Ps,of the city of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented "certain new and useful Improvements in Stove-Grates; and I do hereby delare that the fol- "l lowing is afull, clear,and exact description "of `the invention, which will, enable others Q? Iskilled in the art to which itappertains to make and use the same,reference being had tothe v `acconlpanying drawings, and to letters ofrefv I I I erence marked thereon, which forma part of x thisspecification. f

My invention relatesto improvements in grates for ire-boxesofstoves,\furnaces, &c.

The object of my invention is to provide a I grate for sifting the ashesfrom coal within y y; the fire-box, and also for `dumping the coal i: iorclinkersfrorn the stove after having irst I* e `separated the ashestherefrom, the construcp `tion of `which is`such that itis not liable tobecome choked. up or locked in a rigid posiy "3 tion by coal orclinkers, andwhichis more easily operated and more effectual inaccomyplishing `the end Vdesired I than fthe ordinary rates now inuse.4

position within the y ,fire-box,1 and to `provide he same with acentralshaft or trunnion,by

eans of which rthe* grate could be turned gewise when itis-desired todump the coal-,"-` r partially-sowhenit is` desired` to shake theshestherefrom.y` l y j` i" t is obviousthat theedgesof the horizontal ordat grate are liabletobecomefrequently logged with coal and clinkerswhen being haken, and the coal is falsoliable to escape romthe fire-boxwith the ashes. p p By my device `thebars of the grate move or the coalto escape when shaking, or -for the `or backward, or alternately forwardor acky 'own gravity, toroll upon the ashes as th y J is thev end ofthefire-box, provided with t slightly forward,"` so as to escape contatwith the lugs". Y `no opportunity all of which is further explainedbyreference to the accompanying drawings, in which-f Figure `lrepresents a top-plan view of my invention. Fig. 2 represents a verticaltransy verse section ofthe same. Fig. 3 represents a perspective view ofthe same, having a part ofthe lire-box removed. A

In the accompanying drawings,l like part-s are indicated by the samereference-letters- A is the fire-box, which is provided with a Icylindrical'grate consisting of a series of circular bars or rings, G,connecting bars D, headsE, trunnions F, and longitudinal section G, allof which constituent partsof "thecylinder may be cast in one piece, withthe exception of the longitudinal section G, which is made detachable.

The object of providing the gratewith the detachable section is tofacili-tate the removal of coal or clinkers from the fire-box, wh ich isaccomplished by, removing the detachable V"seci tion and half revolvingthe grate, sothat the contents ofthe fire-box will drop into the ashv.pit'through the space from which] section G l has been removed. 1 v

When the section G is attached the cylinder 1 may be revolved eithercontinuously forward ward coal. Y H isa vmetallic rod or roller, whloosely in the cylinder, and i's caused,

` When" it Ais desired to turn the grate entirely y i over, lor toVrevolve it, the handle is" drawn n .y ratel to Ybecome cloggedwith coalor clinkers,

box are also provided with anges N, which project slightly between thebars C, to prevent coal from escaping from the box.

Having thus described my invention, what I claim as new, and desire tosecure by Let- 1 ters Patent, is-

In combination with n fire-box, A, provided with anges M a-nd flanges Nand lugs K, of the revolving cylindrical grate, consisting of rings C,bars D, provided with heads E, and

trunnions F, all substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

WILLIAM PHIPPS.
